Magdeburg Hemispheres Experiment Apparatus, Cast Iron Physics Lab Teaching Tool for Demonstrating Atmospheric Pressure, with Air Valve and Pull Rings for High School

Product Information

About

Demonstrates Atmospheric Pressure: This Magdeburg Hemispheres Experiment Apparatus clearly shows how atmospheric pressure holds two sealed cast iron hemispheres together once the internal air is removed. Perfect for engaging high school physics students with a classic, hands-on demonstration of invisible air pressure forces.
Durable Cast Iron Construction: Made from solid cast iron with a smooth, burr-free painted surface, this Magdeburg Hemispheres Experiment Apparatus resists wear and ensures long-term classroom use. The interior is coated with rust-preventing paint to maintain airtight performance over time.
Ideal for Science Education: Designed specifically for high school and introductory college physics labs, this Magdeburg Hemispheres Experiment Apparatus helps teachers vividly explain concepts like vacuum, air pressure, and force. Students can even pull on the rings to experience the power of atmospheric pressure firsthand.
Precision Sealing Design: Each hemisphere features a finely machined contact surface that, when greased with the included and rotated properly, creates an airtight seal. The integrated air guide valve allows easy evacuation and re-admission of air for repeatable, reliable demonstrations.
Complete Ready-to-Use Kit: Your Magdeburg Hemispheres Experiment Apparatus comes with one pair of black cast iron hemispheres with sturdy pull rings and a sample of for sealing. No additional parts needed—just connect a hand pump (not included) to start demonstrating the power of air pressure.
